“…In details, it is an extended FSM which can be triggered by specific inputs from the designer. In [9] [10] [11], the authors show different hardware obfuscation methods to prevent hardware Trojan insertion and to assist others detection methods. These invasive methods can be difficult to achieve for a complex IC and they can add increase even significantly the cost of the ICs.…”

Hardware Trojans recently emerged as a serious issue for computer systems, especially for those used in critical applications such as medical or military. Trojan proposed so far can affect the reliability of a device in various ways. Proposed effects range from the leakage of secret information to the complete malfunctioning of the device. A crucial point for securing the overall operation of a device is to guarantee the absence of hardware Trojans. In this paper, we survey several techniques for detecting malicious modification of circuit introduced at different phases of the design flow. We also highlight their capabilities limitations in thwarting hardware Trojans.

Mobile devices have been pervading many aspects of our lives, including applications that are critical and deal with sensitive data. Together with existing features, designers are required to add cryptographic primitives capable of guaranteeing privacy of the users and security of the operations. However, for pervasive mobile devices, the simple addition of cryptographic capabilities is not sufficient.In this paper, we discuss, from the hardware prospective, three main security challenges faced by designers while designing mobile devices: physical attacks, hardware Trojans, and software malware. For the first ones, we report mitigation techniques which can be already applied during the hardware design flow. For the last one, which is mainly related to software, we discuss its potential hardware implications.

“…Obfuscation is a technique that transforms a circuit or design into one that is functionally equivalent but is significantly more difficult to reverse engineer [37][38][39]. Thus, more resources and time will be required for an attacker to determine chip functions.…”
